2019-06-06 05:36:14 -0500	marked best answer	vec3b has more than 3 elements? I was using imread to load a 3-channel png image and accessing the bgr pixel values through: image.at<vec3b>(x,y)[0] image.at<vec3b>(x,y)[1] image.at<vec3b>(x,y)[2] However, I found that vec3b[n] (n>=3) also contain some values. Any ideas on what these values indicate? Shouldn't vec3b only contain three values representing bgr channels?
